deleted, not neccessary, dh_installdirs does it
/var/cache/iptables-optimizer , thats it.
auto-apply now in /var/cache/iptables-optimizer, v0.9.6

more intuitive path is better
v0.9.6 released

path for auto-apply changed to /var/cache/iptables-optimizer
no longer need for a postinst script due to dh_installdirs
